Historical Background

In Norse mythology, Garm was a giant dog which guarded Helheim, the land of the dead. Garm lived in a cave called Gnipahellir. Garm's coat of fur was soaked in blood. He was considered second only to Fenrir in ferocity. Garm is prophesied to kill the god Tyr (Norse god who lost his hand imprisoning Fenrir), who will also kill Garm, in Ragnarok, the Norse end of the world. Note the similarity between Garm of Norse mythology and Cerberus of Greek mythology.
